This example shows how to remove port 1 as a SPAN source for SPAN session 1:
Switch> enable
Switch# configure terminal
Switch(config)# no monitor session 1 source interface gigabitethernet1/0/1
Switch(config)# end
This example shows how to disable received traffic monitoring on port 1, which was configured for bidirectional
monitoring:
Switch> enable
Switch# configure terminal
Switch(config)# no monitor session 1 source interface gigabitethernet1/0/1 rx
The monitoring of traffic received on port 1 is disabled, but traffic sent from this port continues to be monitored.
This example shows how to remove any existing configuration on SPAN session 2, configure SPAN session
2 to monitor received traffic on all ports belonging to VLANs 1 through 3, and send it to destination Gigabit
Ethernet port 2. The configuration is then modified to also monitor all traffic on all ports belonging to VLAN
10.
Switch> enable
Switch# configure terminal
Switch(config)# no monitor session 2
Switch(config)# monitor session 2 source vlan 1 - 3 rx
Switch(config)# monitor session 2 destination interface gigabitethernet1/0/2
Switch(config)# monitor session 2 source vlan 10
Switch(config)# end
This example shows how to remove any existing configuration on SPAN session 2, configure SPAN session
2 to monitor received traffic on Gigabit Ethernet source port 1, and send it to destination Gigabit Ethernet
port 2 with the same egress encapsulation type as the source port, and to enable ingress forwarding with IEEE
802.1Q encapsulation and VLAN 6 as the default ingress VLAN:
Switch> enable
Switch# configure terminal
Switch(config)# no monitor session 2
Switch(config)# monitor session 2 source gigabitethernet1/0/1 rx
Switch(config)# monitor session 2 destination interface gigabitethernet1/0/2 encapsulation
replicate ingress dot1q vlan 6
Switch(config)# end
This example shows how to remove any existing configuration on SPAN session 2, configure SPAN session
2 to monitor traffic received on Gigabit Ethernet trunk port 2, and send traffic for only VLANs 1 through 5
and VLAN 9 to destination Gigabit Ethernet port 1:
Switch> enable
Switch# configure terminal
Switch(config)# no monitor session 2
Switch(config)# monitor session 2 source interface gigabitethernet1/0/2 rx
Switch(config)# monitor session 2 filter vlan 1 - 5 , 9
Switch(config)# monitor session 2 destination interface gigabitethernet1/0/1
Switch(config)# end
